To all whom t may concern.'

Be it known that l, Tontas E. Barren, aE citizen of the United States,` and residing iny and State of New York,` have invented certain new and useful linproyements in Taping-Machines, of which The invention relates to a tape applying:

machine and more particularly to improve-f ments in the construction, arrangement and f gect.-

organization of the parts thereof. v

@ne object of this invention .is to provide a machine having a novel combination of applying mechanisms, cooperating to intermittently feed the i from, and apply the severed portion to thef work by'a rotary movement of the tape applier.

Another object of the inventionis to pro-E vide novel work feeding means, Co-acting with the tape applying mechanism to feed the work into position to receive the tape thereon. f

Acfurther object is to provide a construc-I be rapidly and accurately adjusted to per-l mit 'of the tape being deposited at any de-g` In the accompanying drawings illustrating the preferred form ofthe invention,"E .Figure 1 is a side elevation of the machineg, Fig. 2 is an end elevation looking from the'` front; Fig. 3 is a plan view; Fig. a is a de-l` tailed view of the device for adjusting the; taping mechanism; Fig. 5 is a detailed view; of the adjustable cam of the tape severing r mechanism; Fig. 6 is a detailed view of the tape applying mechanism, per in closed position; Fig. tary view'of the tape applier,

drum and the object, the gripper is -auto matically opened to release the tape and permit of its application upon the object..

v The tape feeding means consist of a driving roll (6) and an idler (7) spaced apart and formed with circumferential grooves (8) through which the tape guides (9) pro- The driving roll (6), which is geared to rotate in unison with the drum (2), is provided with twosegments (10), disposed on either side of the lower guide (9), ywhich serve to press the edges of the tape against the idler'('i) and by rolling frictional 'contact therewith to intermittently advance the endfof the tape to a point above the face of the drum. "The tape, in feeding,.passes between two freely rotating teethed rolls (11) which serve to crack the adhesive coating of the tape and thereby prevent it from .curling.

To .press the end of the tape down upon Vthe surface of the .drum imposition for en`- gagement by the gripper (3)'1 poyide a mechanism comprisinglfa hinged presser the .tape ,and ar? ranged to be 'raised and lowered by the movement-ofthe `forked rod fhaviiig the laterally proj ect-ing pin (14) which'rides on the recessed cam disk (15) rotating with the drum (2). The cam is set with relation to the rotation of the drum so -that the operation of this mechanismy will be timed to press the end of the tape upon the drum just before the gripper is brought into position to engage it.v

Figs. 6,7, and 8, consist of a gripper (3) rigidly ixe'd to the transversely extending spindle (16) which is mounted for oscillation in a bearing block v(17) secured to the inner face of the'rim of the drum (2). The spindle has a crank arm (18) which is secured at itsend to a rod (19) mounted for combined endwise and lateral swinging movement in a support (20) attached to the drum (2). A spring '(21), coiled around the rod (19) -and fastened at its ends respectively to the support (20) and the sleeve (22) fixed to the rod, is provided to thrust the gripper into gripping position, `as here inafter described. The outer end 'of the spindle has an enlarged head (2,3) carrying The tape. gripping means, as best seen in` an outwardly projecting segment (24). In Fig. 6 the gripper is shown in closed position just after it has engaged the end of the tape. From an inspection of this figure it will be seen that as the drum rotates in the direction of the arrow, the end (a) of the segment (24) will strike the pin (25) which is rigidly held inthe path thereof and thereby cause `the spindle to .turn in its bearing so as to throw the gripper (3) into open position, shown in Fig. 7, and release the end of the tape. l/V hen the end (b) strikesthe upper rigidly held pin (26)'7 the spindle will be caused to turn in the opposite direction, thereby carrying the center of the crank arm (18) off the center of the rod (19) and pervinitting the spring (21) to expand to drive the rod (19) upward and the -gripper (3) downward upon the edge of the resilient plate (27) so as to firmly clamp the end of the tape which in the meantime hasyagain been fed into position. `The plate (27) is secured for slight sliding movement in a recess formed in the face of the drum, and is resiliently held therein by the springs 4(28), as clearly seen in Fig. 8. This construction permits'the plate to move backward from under the gripper whenthe latter isdriven home upon it, and to thereby counteract the tendency ofthe gripper to recoil,

The tape severing mechanism consists of a bell crank (29) pivoted as at (30) and provided,at the end of its vertical arm, with a lug (31) which is pressed against the face of the notched cam (32) by means -of a spring (33) drawing on the horizontal arm of the crank. The rear end of the latter arm is connected by a compound lever (34) with the knife (5) so that when the lug (31) enters the notch in the cam, which is arranged to rotate with the drum, the kuifewill be operated to cut a strip from the tape. The cam is fastened by a nut (35) screwed on the threaded end of the bolt (36) which is fixed to t-he drum and projects through the segmentalslot (37) of the cam. Vhen the nut is loosened, the cam may be independ ently rotated to adjust the position of the notch so as to time the actuation of the knife to sever a portion' of any desired length from the tape.

In order to meisten the adhesive surface of the tape, I provide a water wheel which is rotated in the trough Veys the water to the freely turning fountain roller (40) by which it is applied to the strip while it is being carried on the drum. The wheel (38) is preferably mounted in a slidingbox so that its position can be adjuste'd toward or away from the fountain roller to vary the quantity of moisture supplied. i

The form of machine herein described is particularly designed to apply a strip of adhesive tape upon the seam of a folded box (39) and con- (48) whereby the position of the blade -mai .A spindle work supporting table (41) upon which a stack of blanks may be placed in the hopper formed by the two laterally adjustable wings or gages (42) so that the seams vof the blanks will be in line with the center of the taping drum (2). ,Allaterally adjustable pressure shoe (43), having a weight (44) at the end,

1s provided to keep the blanks fiat in the hopper. A

To feed the blanks a pusher blade (45) is employed, and provision is made for actuating the blade to vsuccessively push the lowest bla-nk of the stack into the machine. The blade (45) extends across table behind therear edge of the bottom blank and is provided, at the ends, with pins (46) which fit into gage holes (47) formed in the bars be accommodated to the length of the blank. The bars (48) are slidably supported in the ways (49) disposed at the sides of the table (41) and are each connected by a link (50) with one ofthe upwardly extending arms (51) which are fixed to the rock shaft (52). One end of the rock shaft is provided with a lever (53) which is connected by a rod (54) to the crank (55) of the power driven rotary cylinder (56). The rod (54) is preferably divided into two parts connected by a turnbuckle (57 )v whereby the length of the stroke may be readily adjust-ed. At each revolution of the cylinder, the pusher blade is operated to move forward on the table to thereby shove one of the blanks upon the cylinder and then returned to its initial position for engagement with the neXt blank. The cylinder (56) is mounted directly below the taping drum with its axis parallel thereto and serves'to support and advance the blank while the adhesive strip is being applied thereon by the rotary movement of the drum. I

, The tape applying, feeding, cut off and .moistening mechanisms are all preferably mounted in a single carriage (58)4 which may be moved bodily, from. side to side, to afford lateral adjustment. The carriage is rigidly fixed to two parallel shafts (59) which are provided with racks (60) at their right hand ends and supported for endwise movement in the frame (61) of the machine. (.62) carrying two pinions (63) which mesh with racks (60) and having a hand wheel (64) is provided to effect the lateral adjustment of the carriage.

The taping drum (2) is firmly secured' to a shaft (65) which is given a continuous rotary movement by the gear (66) fiXedto rotate with the power driven cylinder (56) and meshing with the gear (67) which turns looselycn the shaft and has an attached disk (6.8) keyedto slide in the slot (69) formed in the shaft. This construction permits the shaft to move endwise,

' in the latter.

*less belt o r chain (78) blanks travel on 'a' table (74) and, which when adjusting the position of the carriage (58) without disturbing the rotarydrive connections. The gear (67 and disk (68) are fastened together by a bolt (70) pass,- ing through the segmental slot (71) formed By loosening turning` the hand end of the shaft (65) ,the taping drum (2) may be rotatively adjusted about its axis. .Vhen making this vadjustment,the hand lwheelv should be turned in the direction of rot-ation of -the drum so as'not to upset the gripper movement. rIhe'deliver'y endof the'niachine is provided withia'n endunder Whichv the serves to press the adhesive strip firmly. on

blanks are discharged from the endof the table.

It will be understood that -the speciic conj I struction and arrangement' of parts herein shown -and describedy may modified Without departing from-the scope orspiritjof this invent-ion.
